The Pacific Crest Trail is one of the nation's iconic hiking routes. It stretches more than 2,600 miles between Mexico and Canada and this year a record number of people are hiking the Pacific Crest Trail. In fact, as many as 500 are expected to finish the entire trek. From member station KPLU in Seattle, Bellamy Pailthorp reports on how the experience is changing as more people do it.
